  You could also siphon your heating oil into your diesel car, with the problem that you are not paying for your share of road use. It also becomes an interesting conundrum with electric cars.

Of course that also means that if you limit your consideration to the road only, someone driving a lightweight Ferrari that gets 13MPG is really helping out with the cost of roads, even if they are also needlessly contributing a lot of carbon to the atmosphere.

    It would probably be offloaded into yearly registration taxes that are based on the amount of damage your car would create on the road. A heavy truck costs more than a lightweight miata or motorbike. For now, govt. wants to subsidize electric car's introduction to the market, so this tax deduction will probably stay for quite a while.
